Chapter 276 Filling the gap in the country
Yang Dongsheng sat at the top, looked at the group of people below with a lot of humility, and finally sat down.

In the secondary industry despise chain, the machinery manufacturing industry is higher than the mining industry.

Yang Dongsheng still remembers that in his previous life, his company acquired a large machinery manufacturing enterprise that was on the verge of bankruptcy at the request of the government.

In the end, the group of guys who couldn't even eat said to them with contempt, "A group of coal blacks still want to control us?"

At that time, the boss of their company fought wits and bravely with the leader of that machinery manufacturing company, pulling and fighting, and it took several years to subdue that machinery manufacturing company.

Yang Dongsheng didn't have the scale of their company in his previous life, nor the level of their boss, and he didn't have so much time to spend on this kind of shit, so one of the conditions he proposed at the beginning was to transfer the factory leaders of these factories.

"Mr. Yang, let me ask, are you going to buy our factory?" A man in his 50s with a dark red complexion and a dignified look said as soon as he came up.

He kept talking about "our factory", obviously he had already taken the country's factory as his own in his heart.

"I heard that you are interested in the land of our factory, is it true?" Before Yang Dongsheng could answer, another person said first.

"I don't know where you heard these words. I never thought of buying your factories?" Yang Dongsheng was telling the truth. He never thought of buying these factories.

"Mr. Yang, stop playing around with us. The city wants to hand over our dozens of factories to you. It has already spread!"

"Really? I haven't been notified about this yet!" Yang Dongsheng refused to admit it.

"Mr. Yang just said, after buying our factory, what about our projects?"

"What project?"

"Our project with the Provincial Metallurgical Design Institute!"

"Cough, cough, cough..." At this time, a man in his 40s, who was a bit quiet, said, "Let me introduce you!"

Today they are here for two projects in cooperation with the Provincial Metallurgical Design Institute. The first is an oxygen generator.

Oxygen has a wide range of uses. For example, in these iron and steel factories in Shunhe, a large number of converters have been changed from air blowing to oxygen blowing, which requires a lot of oxygen. Yang Jiayun has to compete with others for oxygen almost every day.

The traditional air freezing separation method has complex equipment, high installation requirements, long construction period, large investment and other problems. Pearlescent sand is a lot of money.

In contrast, pressure swing adsorption has low investment, short construction period, low energy consumption, and low operating cost. Although the purity is not high, it is sufficient and has been widely used in industry.

The principle of the pressure swing adsorption method is very simple, that is to use the characteristics of the zeolite molecular sieve to have a stronger adsorption capacity for nitrogen, so that oxygen can be enriched at the other end of the molecular sieve.When the nitrogen adsorbed by the molecular sieve is close to saturation, reduce the pressure on the molecular sieve to release the nitrogen gas, so that the molecular sieve can be reused.More than two adsorption beds can be switched alternately to produce oxygen continuously.

But making it is not so simple.

In later generations, we often see in the news that the localization rate of a certain project has reached 90%, or even 95%, 97%, but it is always a few percentage points away from 100%. If you look carefully, you will find Those that are not localized are usually fans, compressors, pumps, valves, instruments, sensors and other equipment.

The current situation is like this. The compressors and solenoid valves in our country are not good enough, and the level of automation is not enough. As a result, the reliability of our country's pressure swing adsorption oxygen production equipment is poor, and the economic indicators are backward, which is basically unusable.

Since the 80s, our country's PSA oxygen production projects have been suspended one after another, and the gap with foreign countries has become wider and wider.

Another project in cooperation with the Provincial Metallurgical Design Institute is the hot blast stove.

Although our country is the world's largest steel producer in later generations, its profits are meager. This situation will occur. On the one hand, it is true that the upstream iron ore producers monopolize it, and several major mines wantonly raise prices.

But on the other hand, many people have not noticed that our metallurgical equipment is also monopolized by foreign countries, such as hot blast stoves, furnace top equipment, steel rolling equipment, vacuum circulation degassing furnaces, etc. is dependent on imports.

Take Shanghai Iron and Steel Works, a leading enterprise in my country's steel industry, as an example. The blast furnace is basically from Nippon Steel in Japan, and the 2050mm hot rolling mill for further processing is further processed. The mechanical part is from SMS, and the electrical part is from Siemens.

The price of these devices can easily be hundreds of millions, billions, or even higher.

Moreover, these things are not as simple as a one-off sale. If you buy foreign equipment, you also need to buy foreign services. The service fees for many industrial equipment are the bulk.

It can be said that most of the profits are basically taken away by foreigners. After our country's steel industry has left huge pollution, the profit margins are often not easy for foundries known for sucking blood.

……

Apart from the voice of the person introducing, there were only sparse sounds of drinking tea.

Yang Dongsheng will of course support technologies that can break foreign monopoly.

The experience of later generations shows that there is no future for engaging in low-end technology and then engaging in a price war with others.

But on the other hand, Yang Dongsheng has seen many projects in his previous life, under the banner of filling the gap in the country, but in the end they cheated scientific research funds. The "Hanxin incident" is the most famous example.

Especially the group of people in front of them. They had been tossing around for a long time just to divide the seats. Several of them were more powerful than the city leaders Yang Dongsheng had ever seen. Could these projects led by them really fill the gaps in the country? Putting into production means lagging behind?
